摘要： Disclosed are an OLED display panel and a display device. The OLED display panel includes a substrate, a plurality of light emitting components arranged in an array, and a light resistance structure between the light emitting components. The light resistance structure prevents the reflected light of the emergent light from the light emitting components, from emitting out from one side of the substrate between the light emitting components.

摘要： A manufacturing method of a display panel and the display panel are disclosed. The manufacturing method of the display panel generates electric fields between pixel electrode layers or between the pixel electrode layers and electrode layers. The electric fields have a horizontal component and a vertical component. The vertical component of the electric fields provides a force of depositing on the pixel electrode layers for charged groups in a material of light-emitting functional layers. Therefore, the method can prompt an ink of a light-emitting functional material to be deposited on the pixel electrode layers.

摘要： The present invention provides an organic light emitting diode (OLED) display panel and a display device. In the present invention, the planarization layer is disposed with a recess, the anode layer fully covers the recess and extend upward along the sidewall of the recess for a predetermined length. The light emitting layer is disposed opposite the anode layer. When the light emitting layer emits out light, a bottom and a side portion of the light emitting layer in a light emitting region generate light, and the light is emitted out at a corresponding angle to increase light emitting area and angle of the light emitting layer and reduce phenomenon of the color shift of the OLED display panel display screen under a great angle of view to increase a viewable angle of view.

摘要： The present disclosure provides a display panel, including a first pixel group, a second pixel group, and a third pixel group with different colors. The first pixel group and the second pixel group are sequentially arranged along a first direction, and both include four sub-pixels arranged in a matrix. The third pixel group is adjacent to the first pixel group and the second pixel group, and the third pixel group includes at least two third sub-pixels sequentially arranged along the first direction. A demand of products for printing accuracy requirement of a printing equipment can be reduced under a premise that a number of high pixels per inch (PPI) remains unchanged.
